Title: Improvements in or relating to fatty materials
Inventor: COX CHARLES BERESFORD
IPC: A23L5/30
Filed: 1956-04-06
Abstract: <PICT:0810006/III/1> <PICT:0810006/III/2> A process for making solid discrete particles of a fatty material, for example a higher fatty alcohol, such as cetyl or stearyl alcohol, a glyceride, such as glyceride monostearate or stearin, or a fatty acid, such as lauric, palmitic or stearic acid, comprises (a) forcing the melted material through an orifice in streamline flow, (b) submitting the liquid jet so formed to sonic vibrations so as to reduce the jet into discrete liquid particles, (c) allowing these particles to travel a distance at least that required for the particles to solidify, and (d) collecting the solidified particles, which preferably have a size of 1-4 mms. The vibration to which the jet is subjected suitably has a wavelength of from p d to 6d and the velocity of the jet leaving the orifice is suitably from p Nd to 6Nd, where d is the diameter of the orifice in mms. and N is the frequency of the vibrations in cycles per second.  The sonic vibrations may be produced mechanically, but more desirably are produced by an electronic oscillator and amplifier coupled to a vibration generator which is attached to the orifice mounting.  As shown in Figs. 1 and 2, a suitable apparatus comprises a heated tank 1 in which the fatty material is melted, whence it passes, via charge tank 2, to constant head tank 3.  From there the liquid is conveyed to the orifice unit 5 by tubing including a cooling coil 4 which reduces the temperature of the liquid to only 1-2 DEG  C. above the setting point.  The orifice unit contains several orifices 8 supplied by conduits 7, attached rigidly to a mounting bar 9 which is connected by flexible couplings 10 to rigid support 11, and is vibrated by vibration generator 12 mounted at the centre of rigid support 11.  Suitably the orifices are mounted at 30 degrees to the horizontal to provide a jet of such a trajectory that the solid particles obtained fall on to an inclined fabric mesh, curved polished shoot or other collecting device.  If desired, the particles before collection may be made to pass down the inside of a tower up which a cooling current of air is passed.

Title: Improvements in folding tables
Filed: 1937-04-17
Abstract: 480,222. Folding tables. KOVATS, J. April 17, 1937, No. 11005. [Class 52 (iii)] In folding tables of the kind described in Specification 431,272 in which the legs are retained in folded and unfolded position by spring-urged toggle devices, the mechanism for causing movement of one leg by another comprises. links 26 or 46 extending from the region of the corners of 'the table, where they are connected to the toggles, towards the centre of the table, each link being connected with the diagonally opposite leg. As shown, the legs 10 fold perimetrically within the frame 11 being pivoted at 14 to corner brackets 16, toggle links 17, 18 between each leg'and its bracket being acted on by a spring 24 to retain the legs either extended or folded. A pin. 35 on the toggle link 18 engages a slot 34 in a flange 32 on a lever 27 pivoted at 28 to the bracket 16 and connected at 26b to a link 26. The other ends of the links 26 are pivoted to the arms of a cruciform rooker plate 26<1> mounted at the centre of the table top. Movement of any one leg is thus communicated to the other three. For breaking the toggles simultaneously each lever 27 is provided with a handle 36 pivoted to it at 26b and arranged to abut a fulcrum 38 in the extended position of the legs, Fig. 5. By rocking any handle 36 towards the frame 11 the levers 27 are moved to break the toggles, moving the legs slightly away from the unfolded position so that any one of them can be turned to the collapsed position, causing simultaneous movement of the others. Fig. 7 shows a modification in which pairs of diagonal links 46 connect opposite levers 39 pivoted at 43 upon the corner brackets 16, each lever 39 having a slotted flange 42 engaging a pin 45 on the toggle link 18. Movement of one leg thus operates the opposite leg and by interconnecting the links by a floating cruciform member 48 movement of one leg may operate the other three. Handles 47 are pivoted at 21 to the brackets 16 and the toggles are broken by moving one of the handles upwardly so that a flange on it contacts with and moves the link 18.
